Abstract
An RFID webstock containing a relatively high pitch-density array of semiconductive chips is provided and joined to a web bearing relatively widely spaced antennas in a continuous process. The RFID webstock is separated or cut into individual chip sections, with the spacing of the chips being increased as the RFID webstock is die cut. The individual chips on the sections are then joined to corresponding antennas to form an RFID inlay stock. This process is conducive to high speed roll-to-roll production of RFID tag and label roll stock.
Claims28
A method of forming RFID articles, the method comprising:
- separating at least one section from an RFID webstock having a plurality of sections, wherein the sections each include one or more electrical connectors coupled to respective RFID chips;
- transporting the at least one section on a transport member;
- and
- following the transporting, attaching the sections to an antenna web such that a chip of the at least one section is electrically connected to a respective one or more antennas on the antenna web;
- wherein the attaching occurs while the antenna web is moving.
A method of manufacturing RFID articles, the method comprising:
- in a single manufacturing system,
- forming a plurality of antennas on a substrate to thereby produce an antenna web;
- separating sections from an RFID webstock, wherein each section includes one or more electrical connectors coupled to respective RFID chips;
- and
- attaching each section to the antenna web such that the chip is electrically connected to respective of the antennas.
A method of forming RFID articles, the method comprising:
- separating sections from an RFID webstock, wherein each of the sections includes one or more electrical connectors coupled to respective RFID chips;
- and
- attaching the sections to an antenna web such that the chips are electrically connected to respective antennas of the antenna web;
- wherein the attaching includes securing the section to the antenna web.
A method of producing an RFID product, comprising the steps of:
- advancing a first web having a plurality of RFID sections, with each RFID section having at least one chip;
- advancing a second web having a plurality of antenna sections, with each antenna section having at least one antenna;
- separating said first web into discrete RFID sections;
- applying each of said RFID sections to a distinct antenna on said second web to form a third intermediate web;
- and
- advancing said third web to a collection point.
